deep-isin 1.0.1

this checks key or value in dict(or list)

deep_isin

deep_isin is a Python package that allows you to safely check whether a specific value exists in nested data structures such as dictionaries, lists, tuples, and sets. It also safely handles circular references to prevent infinite recursion.

Installation:

pip install deep_isin

---

Usage:

1. Import the entire module:

import deep_isin

data = {123: [1, 2, {456: [7, 8]}], "abc": (9, 10)}

print(deep_isin.isin(data, 7))    # True
print(deep_isin.isin(data, 99))   # False

2. Import the function directly:

from deep_isin import isin

data = {123: [1, 2, {456: [7, 8]}], "abc": (9, 10)}

print(isin(data, 456))   # True
print(isin(data, 0))     # False

Features:

• Works with nested dictionaries, lists, tuples, and sets.
• Checks both keys and values in dictionaries.
• Handles circular references safely to avoid infinite recursion.
• Can handle any mix of nested Python data structures.
